Disk Utility: Owners Disabled on External Disk

Hello,

I have a same problem. Unfortunately in my case restarting didn't help. I have external disk split into two partitions:

1. External - for all documents

2. Time machine

I accidentally disconnected external disk without unmounting it and afterwards disk "external" won't show up in finder. I can find it through disk utility where it says Owners: disabled. I can only read the disk, I cant write anything on it. I cant repair it (icon is inactive).

Any suggestions?

Thanks

Hi Eric,

sorry but this dont solve my problem. I can see and even open partition "external" through disk utility, but I cant write on it. Owner for this partition are disabled. On the other side 2nd partition "virtual machine" has owners - enabled.

Therefore two main problems:

1. Owners - disabled for partition "external"

2. Partition "external" is not showing in finder (but it is mounted, when checking with disk utility)

Do you know how to handle the problem?

Thanks

JK

On my Mac I am running Two External Hard Disks. One is a WD Passport plugged into the USB 3.0 port and the other a LaCie Rugged Thunderbolt plugged into the thunderbolt port. My GUID Partition Maps Mac OS Extended(Journaled) partitions have Owners Enabled. My MBR NTFS and MS-DOS partitions appears to be Disabled by default. Does not effect the operation of my System. Read/Write, Mount/Unmount and shows on desktop, finder and disk utility just fine.

Cheers!!

well, ok, perhaps ownerhip does not affect ability to write/read on disk. However since accidental unplugging of the disk the partition "external" is not showing in finder and when I open it over disk utility it dont let me write anything on it.

Any idea how to fix this problem? Any kind of recovery?

Go into the Apple Menu and click Force Quit. Force Quit all running tasks. Then click on Finder and click Relaunch button. After that Upper Menu Go>Recent Folders click Clear Menu. Restart. Plug up the external and see what you get. If you unplugged while the disk was writing or reading (let's hope not) is when you run into problems.

Cheers!!

See mount section in 1st linked article.

Disk Unmount Using Terminal

Disk Utility – Force Mount Disk

With the volume elected in Disk Utility, does the button say Mount or Unmount?

If Mount, and you click it, what happens?

unfortunately that didn't help. any other idea how to fix the problem? I really dont want to erase all my data I keep on external disk...
